What are examples of homogeneous and heterogeneous mixtures?
How about the air we breathe as an example of an homogeneous mixture...?
And in a homogeneous mixture, the components are in the same phase. And certainly the air is a homogeneous mixture of dinitrogen, dioxygen, and a few other gases. Most alloys are homogeneous mixtures, for instance brass, or solder, or bronze.
And as for heterogeneous mixtures, we might cite mayonnaise, or hollandaise sauce, the which are emulsions...or ice in water, in which clearly there are two phases present.
